MEAN WELL Develops Miniature DALI-2 Certified Digital Dimming LED Driver

MEAN WELL’s XLG series LED driver complies with the latest safety standards and has an isolated dimming design, covering both constant current and constant voltage applications. The miniature XLG series adopts a double-sided PCB layout design, which can reduce the power supply size and provide better product reliability. The compact size is also convenient for customers to use with various luminaire designs. In addition, the XLG series provides 3-in-1 and DALI-2 dimming functions to offer a more complete solution for intelligent system integration.

DALI (Digital Addressable Lighting Interface) is a protocol described in the technical standard IEC 62386 for digital control of building lighting systems. As the digital lighting evolves, the DALI Alliance (DiiA) developed the DALI-2 certification program; All of the certified DALI-2 products would be more compatible and interoperable to avoid pairing issues between various manufacturers. The newly added products that meet the DALI-2 dimming standard have included a full series of XLG-50/75/100/150/200/240/320W; provide a variety of indoor and outdoor LED lighting for DALI system integration. Also, an additional set of 12V/250mA auxiliary source output can be selected for products above 150W, which would lower the risk of being damaged by surge conduction.

The XLG series adopted a constant power design that is convenient for customers to use in different output currents. In order to prevent the defective issues caused by the abnormal temperatures, MEAN WELL redefined the over-temperature protection so that the LED driver would derated to 75~50% when the temperature increased. In addition, the XLG series also provide IOVP (Input Over Voltage Protection), which would automatically shutting off the LED driver when the input voltage is higher than 320 VAC, to avoid power failure damaged by excessive AC input voltage.

The XLG series meets international certification for customers marketing and selling their luminaires globally. The LED driver can be used with general constant current luminaires such as street lights, floodlights, bay lights or general 12V/24V/48V constant voltage LED strips.
